城市建设中建筑扬尘对环境中PM2.5浓度影响较大,设计一套建筑工地环境监测系统,实现对建筑工地环境的实时监测.基于嵌入式技术、传感器技术,设计环境数据采集节点、监测终端,设计数据监测服务器三部分组成二级监测网络.数据采集节点与监测终端之间通过WiFi无线通信方式实现数据传输,监测终端与数据监测服务器之间通过3G网络构建数据连接.监测系统可以实现建筑工地环境参数及图像的实时采集和报警,性能稳定,且实现数据的远程发送.系统设计合理、安装方便、节能环保、具有良好的可扩展性,能够满足建筑工地安全性、可靠性的需求,实现建筑工地环境情况的监测、报警.%Because the construction dusts produced in the process of urban building have a great influence on concentration of PM2.5 in the environment,a construction site environmental monitoring system is designed to realize the real-time monitoring for the construction site environment. The environment data acquisition node,monitoring terminal and data monitoring server are designed on the basis of embedded technology and sensor technology to constitute a two-stage monitoring network. The data trans-mission between data acquisition node and monitoring terminal is realized with WiFi wireless communication mode,and the data connection between monitoring terminal and data monitoring server is constructed by means of 3G network. The monitoring sys-tem can realize the real-time acquirement and alarming of parameters and image data of construction site environment,and im-plement the remote sending of data,and has stable performance. The system has reasonable design,easy installation,energy saving,environment protection and perfect expandability,can meet the requirements of construction site for safety and reliabili-ty,and realize the monitoring and alarming for the environmental conditions of construction site.
